The metric system is a system that is used wolrd wide except for the United States and two other very small countries. The metric system is used in kilometers instead of miles and meters instead of feet. The united states does not want to change to the metric system because if they were to change to the metric system it would take alot of time and money. The metric system is a much more difficult system from my perception. It might be easier to you, but threw my eyes i find i much more difficult.
